/ flushed from wheels, running gear and mud guards by driving the vehicle to be washed into, around and out of the bowl. With this and other objects in view, my invention comprises the features of construction and combination of parts hereinafter more particularly described and claimed.

In the accompanying drawing forming part of this specification, Figure 1 is a plan of my invention; Fig. 2 is a section taken on the line 2-2 of Fig. 1, showing a portion oi my improved washing bowl; Fig. 3 is a central cross section taken on the line El tl of Fig. 1, and l is a section taken on the line 3-3 of Fig. 1, showing a detail of the drain and overflow ducts.

My invention comprises a shallow bowl forming a wide reservoir and having a floor or bottom 10 and a side wall 11, said side wall in the construction illustrated being substantially of circular shape and the floor sloping downwardly toward the centeof the structure. Where the vehicles enter and leave the bowl. ramps 12 and 13 are provided with suitable grades, so that there will he no loss of. water when vehicles a re entering or leaving the bowl. This entire structure may be formed and constructed out of cementitious material, or out oi any other suitablematm'ial desired. The bowl is equipped with a valve controlled water supply pipe 1 L an overflow pipe 15. and a suitable scttling basin 16 near the center of the structure, over which a removable grate 17 is placed. The duct 15 enters a drain pipe 15, said drain pipe being connected with the. bot tom of the bowl and opened and closcd by a valve 21. The valves closing the supply pipe and drain pipe are controlled respectively by the handle '18 and the handle 19. the latter being connected with its valve 521 by suitablc valve. gearing 20, drive rod 2H". cam 20" and cam operated valve stem 20".

Serial no. 371,215" V running gear, etc. are made to t *avelz'trounl in the bowl as often as is necessary-to ,dissolve and flush off the dirt. The bottom of the bowl which slants toward thogcentei gives greater depth for emersion of the wheels and running gear near the center of the bowl. liy slanting the floor of the bowl toward the center, the water will deposit all heavy material in the settling basin. Any silt or mud zulhering to the main area or the bowl can also be more easily flushed down into the settling basin with a stream of water from a hose. W hen the settling basin be'comes filled with silt, etc., the grate canf be removed and. the accunmlated mud can be shoveled into a (lump wagon and hauled away. The drainvalve can be opened or closed from a distant point by use of the structure illustrated, thus enabling an at tendant to control the operation of the drain valve witl'iout having to enter the bowl.

in accordance with thepatent statutes, I have described the principles of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it umlerstmul that the construction shown is only illustrative, and that the invention can be carried out by other means and applied to uses other than those set torth within the scope of the following claims.

Having described my invention what I claim as new and desire to protect by Letters Patent is:

'i. in a device of the class described, a shallow receptacle tor a washing fluid providing an endless submerged course tor vehicles, said course sloping downwardly and inwardly to a central area, said area being depressed to term a settling basin, the inclination at said course serving to aid drivers in the management of their vehicles anc also serving to direct silt accinnulating from the vehicles toward the settling basin during the aritation ol the liquid by the moving vehicle.

2. in a device of the class described, a shallow recc 'itacle for a washing fluid pro viding an cndlcss submcrgcd course for vehicles. said course sloping inwardly and downwardly to a central area. said area being dcprcsscd to form a settling basin and a drain duct located centrally within said settling basin and opening at the. lcvcl of the top thereof. whereby the fluid entering Said duct first passes over the basin. i

ti A deviceof the class described, comprising a shallow receptacle for ajwashing fluid, said receptacle providing an endless submerged course for'vehicles, and spaced entering and leaving ramps leading to and from the receptacle in tangential directions with respect to said course. v

' 4. A device of the class described, comcomprising a shallow receptacle fora washing. fluid, said receptacle providing an endless subme'rged' course for vehicles and 'a' ramp leading into the receptacle in a tangential direction With respect to said course.

5. A device of the class described, comprising a shallow receptacle for a washing fluid, said receptacle providing an endless submerged course for vehicles, and a ramp leading into said course at a relatively small angle with respect thereto.

6. A device of the class described, comprising ashallow receptacle for a washing -fiuid, a ramp leading into said receptacle,

the bottom of the receptacle providing an endless, submerged, dished run-way for vehicles propelled therein.

7. In a device of the class described, a

shallow receptacle for a washing fluid furnishing an endless submerged course tor veholes, a settling basin, saldcourse belng sloped toward said basin and a drain duct leading from the receptacle and opening at a point above the bottom of said basin.

'8. A device of the class described, com- I prising a shallow receptacle for a washing fluid having means of ingress and egress CARL P. BOHLAND.
